SQL Server存儲過程和用戶​​查詢之間的區別

Question

我們有一個存儲過程，它從幾個不同的表中提取信息以顯示一些信息。這工作正常。

我們現在想要「借用」一些代碼，我正在嘗試做一些開發工作。當我將存儲過程的內容複製到查詢窗口並運行它（減去存儲過程相關的東西）時，它會成功完成，但不會返回任何結果 - 事實上，＃test2未被填充。通過存儲過程運行相同的結果通常會返回結果。

代碼從下面的查詢 - 存儲過程是相同的只是ALTER PROCEDURE，我已經改變了所有的表名等等

Answer 1

需要引用日期'：

DECLARE @reportstart smalldatetime, @reportend smalldatetime;     

SET @reportend = '2016-01-01'; 
SET @reportstart = '2016-02-01'; 

否則你會得到DATE從INT隱式轉換是一年1905

它的工作原理類同此：

SET @reportend = 2016-01-01; 
--SET @reportend = 2014 -- int 
--SET @reportend = DATEADD(d, 2014,'1900-01-01') 
--SET @reportend = '1905-07-08 00:00:00' 

我高度懷疑，你從1905
